An Unusual Presentation of a Huge Nabothian Cyst of Cervix With Manifestation of Uterine Prolapse: A Case Report.

backgroundNabothian cysts are common benign cervical lesions in women of reproductive age. They usually occur due to childbirth or minor trauma; mostly are small and asymptomatic. However, huge nabothian cysts may have variable presentation and can even mimic malignancy thus, biopsy is recommended to rule out malignancy. The unusual presentation of nabothian cyst as uterine prolapse makes it a diagnostic challenge for management of the patient similar to the present case. CASE REPORT: We report a case of a huge nabothian cyst in a perimenopausal, multiparous woman who presented with complaints of something coming out of vagina suddenly after mild heavyweight lifting and pain abdomen. Pelvic examination revealed a second degree uterine prolapse with a large lump protruding outside the vagina. Transvaginal ultrasonography demonstrated a multicystic cervical mass of size 9.5 cm × 8.0 cm arising from the posterior lip of cervix that was protruding through the vaginal canal. After excision of mass, prolapse became first degree. Histopathologic diagnosis was a cervical nabothian cyst. Patient had persisting first degree uterine prolapse along with posterior vaginal wall prolapse on subsequent postoperative follow ups. Hence, vaginal hysterectomy with repair to the vaginal wall was performed later.

conclusionThe present case of nabothian cyst is reported for its unusual presentation as uterine prolapse. The risk factors for pelvic organ prolapse (POP) in the present case are advancing age, multiparity and perimenopausal status. The connective tissue and levator ani muscle became weak and the nabothian cyst unmasked the POP that was latent and asymptomatic by increasing the prolapse from first degree to second degree.
